Our valve bodies are dynomometer-tested on our Answermatic 4000 Valve Body Test System using Superflow WinDyn software and are built in-house, specifically calibrated to work with Goerend torque converters along with other products of ours. We offer constant pressure and manual valve body setups. Please take the Valve Body Questionnaire to set up a custom valve body to fit your truck's specifications.

Some valve bodies are limited on how much line pressure that can be run due to the stretching and deformation of the torque converter's impeller due to over-pressurization, known as ballooning. Our apply-regulated valve body regulates torque converter lock-up apply pressure separately from main line pressure. This allows higher pressures in the transmission for holding smaller diameter converter clutches, while a lower, safe pressure is used to hold the large diameter converter clutches without damaging the torque converter, pump, or shaft.

This apply regulation can be added to any Goerend valve body and can be set up for racing applications or for daily driver towing. Testing has shown a significant decrease in the harshness of the 3-4 shift that 3rd generation trucks are known for when adding a triple disc torque converter. Additional parts required: 48RE pump stator support seal, Goerend triple disc torque converter.

We utilize a technique that has been in the gas racing world for years, the torque converter dump valve, which drains oil from the torque converter while spooling at the line, allowing the engine to gain RPM and rise to the desired level before launching. When coupled with a Goerend non-lock torque converter and constant pressure manual trans-brake valve body, drivers have seen faster and more consistent runs. The dump valve setup requires no major changes to the transmission, only additional wiring to control the solenoids. Other advantages to this system are less rotational weight and overall maintenance, with higher pressure to hold the transmission clutches and no torque converter clutches.

WHAT MAKES A GOEREND VALVE BODY DIFFERENT THAN THE COMPETITORS OR DIFFERENT THAN INSTALLING A VALVE BODY KIT?

We like to keep shifts smooth as possible. Not a slippery long drawn out shift, but a quick and smooth shift. When you step into the throttle and the engine power increases, the pressure in the transmission also needs to increase. Our valve bodies have a much faster and steeper pressure rise than other valve bodies. A factory valve body normally has idle pressure of 60 PSI and wide open throttle pressure is near 100 PSI. Goerend valve bodies will start at 70-90 idle PSI, depending on truck, and the pressure rise to 150-190 PSI at wide open throttle.

WHEN ACCELERATING AT ¾ THROTTLE AT 40 MPH, MY TRANSMISSION SEEMS TO SHIFT TO NEUTRAL & THE ENGINE REVS TO REDLINE.

Some trucks have a problem while accelerating at about ¾ throttle around 40 MPH. The transmission will neutralize and the engine will rev up, just like it shifted to neutral instead of 3rd gear. If the throttle is then let off, it bangs into 3rd gear. A Goerend valve body will correct this. Many trucks have gear hunting from 2nd to 3rd. As long as the governor solenoid is in good condition, a Goerend valve body corrects this. Most people who build valve bodies do not know that the torque converter circuit is regulated to 130 PSI from factory. It is common practice to eliminate this circuit and give the converter full line pressure. This is not good and is the main cause of ballooned converters. A Goerend valve body has the proper regulation in the converter circuit.

WHAT IS THE DIFFERENCE BETWEEN A TOWING, SLED PULLING OR DRAG RACING VALVE BODY?

On a towing valve body we want a smooth shift. This helps keep shafts and planetary gears from breaking due to the high shock of brutal shifts. We also build the valve body so you can downshift from 4th to 3rd and from 3rd to 2nd with the converter locked in case you have an exhaust brake. If a toggle switch is installed you can also lock the converter while in manual 2nd so the converter will not overheat while towing a heavy load up a steep grade.  

On a sled pulling valve body you most likely will want the converter clutch to be capable of locking in 1st, 2nd, 3rd and overdrive and also be able to back shift from overdrive to 3rd, 2nd, 1st with the converter locked.

On a drag racing valve body we normally lock the converter right after the 1-2 shift. We can build the valve body so it will not lock the converter in 1st. That way you can turn the lock-up switch on while at the starting line and it will not kill the engine and as soon as it shifts to 2nd the converter will automatically lock up.  

IS THERE ONE VALVE BODY THAT WILL WORK WELL FOR DAILY DRIVING, TOWING, DRAG RACING AND SLED PULLING?

Yes and no. Up to about 500 HP you can use the same valve body and it can work well for all. Once above that, there are things we need to modify on the valve body that would be specific to drag racing and sled pulling that would not be done to a daily driver or tow rig.

DO ALL VALVE BODIES NEED THE EXTRA SPRING FOR THE FRONT BAND APPLY SERVO? 

All Goerend valve bodies need the spring. We do make valve bodies that are not as high a pressure and do not require the extra spring. These valve bodies have all the same upgrades as the high pressure valve bodies - only with pressures that are slightly above stock. These valve bodies are for people who want to install a valve body only and do not have to remove the trans to install the billet 1-2 shift lever.

WHAT IS A CONSTANT PRESSURE VALVE BODY AND WHY WOULD ONE BE NEEDED? 

Normally the pressure that applies the clutches and bands in a transmission will be low at idle and high at wide open throttle. With a Goerend constant pressure valve body, the pressure is high at all times, both at idle and wide open throttle. A constant pressure valve body is normally used for trucks that are racing or with engines that have high power.

WHERE DOES THE BIG SPRING GO THAT COMES WITH THE NEW VALVE BODY? 

This spring goes into the front band apply servo along with the original spring. This is the servo that applies the front band.

CAN A VALVE BODY BE INSTALLED WITH A STOCK 2ND BAND APPLY LEVER?

We have seen the stock 2nd band apply lever break with stock valve body pressures, not often, but we have seen it happen. If a valve body is being installed with higher pressures we recommend you remove the transmission and install a lever made with a stronger material. We do make a stock pressure valve body with all the other features in our high pressure valve bodies.

WILL A NEW VALVE BODY CURE ALL MY SHIFTING PROBLEMS? 

Many shifting problems can be cured by a valve body, but the shift timing is controlled by the computer. On a 1995 and older, the 3-4 and converter lock up is computer controlled. On a 1996 and newer, all shifts are controlled by computer, so if you have a bad input to the computer, such as a bad throttle position sensor or output shaft speed sensor, they can affect the shifting and that would seem like a valve body problem even though it is not.

WHAT ARE THE PRESSURES ON OUR VALVE BODIES? 

A Goerend valve body can have pressures ranging from 70 PSI at idle to 190 PSI at wide open throttle (WOT). Driving habits and truck use will dictate what pressures are needed. We also have constant pressure valve bodies where the pressure is fixed, the pressure is the same at idle as it is at wide open throttle.

VALVE BODY APPLICATION/ORDER INFORMATION

Goerend High Pressure Valve Bodies are designed to run with a Triple Disc Torque Converter, a billet input shaft, a 3.8 ratio front band apply lever, and a Goerend heavy front servo spring. If there is any variation from the above mentioned features, modifications will need to be made to the valve body to accommodate.

    Perfection on every build

    Posted by Brian Wilson on May 31st 2017

    Every valve body is built specific to application when ordered. Perfect crisp shifts and never a issue right out of the box and into the trans. Only valve body offered in our builds.

    Perfection in every single built unit

    Posted by Chris Snyder on Mar 17th 2017

    I have never once in hundreds of Valve bodies had a single complaint about how awesome the shifts feel after the staff works their magic prior to shipment. Thank you for such an awesome upgrade!!!

    I have this vb in my 04.5 cummins with the gt2 rebuild kit and goerends triple disc converter. Never had a problem out of any of it in 4 years.
